It's ok, let's try this one step at a time. First, let's see what types of mods are 'orphaned'. I'm not really interested in 'what' they are per se, or how many- just looking to see which ones might be 'critical'.
We can try
this, but the odds are it'll corrupt the game save, or if it loads the game might ctd or lock up. Be sure to wait for the video to upload and HD processing to complete, otherwise it'll be super-low res and impossible to watch.
Good luck, and let me know how it goes.
